The aminoglycosides are products of Streptomyces species and are represented by streptomycin, kanamycin, tobramycin and gentamicin.

What class of antibiotics is tetracycline?

Tetracyclines (tetracycline, doxycycline, minocycline, tigecycline) are a class of medication used to manage and treat various bacterial infections. Tetracyclines classify as protein synthesis inhibitor antibiotics and are considered to be broad-spectrum.
